Panchang in Ipameri, Goiás, Brazil Wed 4 Aug 2021

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:38 on Tue 3 Aug and 06:37 on Wed 4 Aug. Ekadashi (04:30 Tue 3 Aug to 06:47 Wed 4 Aug) and Dwadashi (06:47 Wed 4 Aug to 08:39 Thu 5 Aug) are both longer than their day; when both grow, Smartas take the later day: Wed 4 Aug. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Kamika Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 06:37 here. Dashami ended at 04:30 Tue, before it. Ekadashi ends at 06:47, when the lead reaches 312°. The lead passed 180° at the full moon of 23 Jul, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:30 Tue, before sunrise at 06:38 Tue, and ends at 06:47, after the next sunrise at 06:37. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Tue 3 Aug ran from sunset 17:59 Tue to sunrise 06:37, 12 h 38 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:37 to 18:00, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 06:37 Thu, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 3 at 60°. It leaves at 19:54, for Ardra.

Add the Sun's and the Moon's places among the stars: 108.1° + 60° = 168.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 16:20, then Harshana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava ended at 17:41 Tue, when the lead reached 306°; Balava runs until 06:47.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:37 to 06:37 Thu, so the hours after midnight still belong to Budhawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 8 Aug, finds it in Karka and begins Shravana.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 8 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 2021, 23:30 Sun. Since then the Sun has moved 109.8° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
